Description

A kind of curl arched mole
Technical field
The invention belongs to hydraulic engineering field, more particularly to a kind of curl arched mole.
Background technology
Breakwater is broadly divided into two kinds of vertical type, ramp type forms by its form of fracture.
Vertical breakwater is typically made up of wall body, superstructure and basis, and basis is mostly rubble-mound foundation.Because wall body hangs down Directly, material usage is less, occupies little space, and harbour can also be doubled as on the inside of dike, easy to use, but wall body stands on basis vertically In, equivalent to cantilever design, foundation stress is big, therefore it is required that ground is solid, has good bearing capacity.Because wall body hangs down Directly, the sizable wave of flow velocity is acted directly on wall, very high for wall body quality requirement, and the reflection of wave is big, Therefore wave absorbing effect is poor, and the calmness in waters in port is can also affect on when serious.
Sloping breakwater is typically made up of dike cardiolith, mask and river bottom protection.Because mask is slope, it is sometimes provided with staggering Platform, the cross dimensions of breakwater is larger, and wave absorbing effect is good, and wave does not reflect largely, and to the bearing requirements of ground not It height, construction is simple, can gather materials on the spot, all not need large-scale crane gear typically, but material materials are more, armor stone Easily being washed away by wave, it is necessary to often repair, later stage expense greatly increases, and for waters of the depth of water more than more than 10m just No longer it is applicable.
In addition, also there are the breakwater of some special shapes, such as the breakwater such as exposed throughout type, floating, jet-propelled.But These special shapes, it is exactly that reliability is low or investment is big if it were not for temporary project is only applicable to.
The content of the invention
The purpose of the present invention is that to develop a kind of wave absorbing effect good the defects of overcoming traditional breakwater, saves material, construction party Just, widely used curl arched mole.
To realize that technical scheme that the object of the invention uses is a kind of such, curl arched mole, including levee body, Spats, seepage proof curtain, counterfort, pier and back filled region I.
The levee body, spats, seepage proof curtain, counterfort and pier form by concreting.
The spats elongated distribution along the coastline, and pouring molding is in basic stratum.The lower end of the spats is disposed with Seepage proof curtain.The seepage proof curtain is deeply to the impermeable stratum on basic stratum.
The levee body is located at the top of spats.The levee body is arch, and the inner concave of arch is the working face of breakwater, arch The arcuate surface of shape is the back side of breakwater.The back side of the levee body backfills the back filled region I that some building stones form ramped shaped.
The top of the back filled region I has some pieces of counterforts.The counterfort is that bar shaped of the skewed horizontal load at the levee body back side mixes Concrete board.It is spaced apart between every piece of counterfort.An intersegmental gap is left between the counterfort and back filled region I.Every piece of counterfort Rear side is provided with a pier.The pier branch blocks the bottom of counterfort.
Further, in addition to back filled region II, back filled region III, step and guard rail.
Building stones are backfilled between the bottom of the counterfort and pier and form back filled region III.The height of the back filled region III and pier it is upper Flush.The rear side backfill building stones of the pier form the back filled region II of ramped shaped.Inclined-plane, pier of the step along back filled region II Lay to levee crown on the inclined-plane of upper surface, counterfort with back filled region III.The top of the levee body is plane.The both sides of the step with And levee crown both sides set guard rail.
Further, the seepage proof curtain gos deep into 5m below velatively waterproof layer, or it is high 1/3~1/ of dike to go deep into depth 2.The seepage proof curtain is arranged to two row's grout curtains, and wherein curtain array pitch is 1m, is 2m with the spacing arranged between curtain;Two rows Curtain dislocation arrangement, dislocation distance 1m.
Further, the strength grade of concrete of the levee body is not less than C30, and seepage-resistant grade is not less than W8.
Further, the levee body sets the wide subsiding cracks of a 20mm every 15~20m, is filled out in seam with pitch wood wool board It is real.
Further, the cross section of the spats is length of side 2m square.
Further, the height of the levee body is 10~15m, and wall thickness is 2~5m.The thickness of the counterfort is 1m, and adjacent 5m is spaced between counterfort.The pier is 1.5~2m of length of side square.
Advantages of the present invention and effect are:Described curl arched mole is when bearing water pressure, due to its curved surface Arcuate boundaries, water pressure can be decomposed into two power of horizontal direction and vertical direction.In the presence of equal wave force, curved surface Water pressure is equal in magnitude suffered by the water pressure and vertical breakwater of horizontal direction suffered by arcuate boundaries, but curved surface arcuate boundaries Vertical direction is the weight of curved surface arcuate boundaries internal water also by downward effect of water pressure, size, is advantageous to the steady of levee body It is fixed, and curved surface arcuate boundaries can also eliminate part energy by changing the direction of motion of wave.In a word, curl arch is prevented Ripple dike effect of energy dissipation is better than vertical type breakwater, and simple in construction, easy for construction, than ramp type breakwater save material and into This, is widely used.
